Purpose: To determine and compare the auditory beha-vior of temporal resolution in subjects with symmetrical and asymmetric sensorineural hearing loss, individuals with brain injury and normal individuals. Methods: Thirty eight
subjects divided into four groups: 11 individuals with sym-metrical sensorineural hearing loss (GPS); four individuals with asymmetric sensorineural hearing loss (GPAS); eight subjects with lesions in the temporal lobe (GL); 15 subjects in the comparison group (GC). These patients underwent he-aring assessment to define the auditory characteristics of the groups, and evaluation of auditory temporal resolution skills through the tests RGDT and GIN. The results of this evalu-ation were statistically analyzed and the responses obtained
were compared between groups. Results: The hearing level
of each ear in the groups GPS, GL and GC are symmetrical. The comparison (GC) and brain injury (GL) groups are similar regarding the audiometric results. We observed a statistically significant difference between comparison, GC, and study groups: symmetrical hearing loss (GPS), and brain injury (GL) for the tests RGDT and GIN. Between the groups
